The electric slide rail 44 can be controlled to descend by driving the electric telescopic rod 43, so that the two groups of flexible clamps 45 can be adjusted according to the height of the roots of the vegetables.

[0028] Working principle: When installing the cultivation rack assembly 13, first splice the two sets of integrated placement racks 133 through the protrusions at the connection, and then place the spliced ​​placement rack 133 on the surface of the support rack 131. After ensuring that the thread grooves are aligned, use a special tool to rotate the bolt b132 so that it passes through the support rack 131 and is threadedly connected to the inner wall of the thread groove of the placement rack 133, thereby firmly fixing the placement rack 133 on the support rack 131, which is convenient for stably placing the cultivation plate 14. In addition, the hook 134 at the bottom of the placement rack 133 can be used to hang mushroom bags or dry vegetables, etc., which increases the functionality and flexibility of use. The modular design of the placement rack 133 is convenient for individual replacement when one side is damaged, thereby reducing maintenance costs.

[0029] When harvesting vegetables, first, the electric guide rail a41 drives the slider 42 to move to a suitable position through the internal electric control unit, and then the electric telescopic rod 43 is extended and retracted to control the electric slide rail 44 to descend, so that it is adjusted to a suitable position according to the height of the vegetable roots. Then, the internal electric control unit of the electric slide rail 44 drives the two sets of flexible clamps 45 to move closer to each other to clamp the vegetable roots. Then, the motor 151 is started (the bidirectional threaded rod 152 can also be rotated manually, and the operation mode is selected according to the actual situation). The motor 151 drives the bidirectional threaded rod 152 to rotate. Due to the surface of the bidirectional threaded rod 152 There are two sets of threads with opposite rotation directions, so the two sets of cutting knives 153 will move closer to or away from each other on their surfaces, and the knife body part slides along the surface of the cultivation plate 14 to cut and harvest the root position of the vegetables, realizing efficient and accurate harvesting operation, and then the electric telescopic rod 43 is retracted, and the electric guide rail a41 drives the slider 42 to move again, and the clamped vegetables are transported to the inside of the vegetable collection box 3, realizing automatic collection of the cut vegetables, which is convenient for the staff to carry and process later, and the slider 42 can hide the flexible clamping plate 45 when it moves to the far right to avoid affecting the sowing operation of the sowing component 5. First, according to the size of the vegetable seeds to be sown, the bolt a54 can be removed by a special tool to replace the filter plate 53 of the appropriate aperture to ensure the accuracy of seed screening. When sowing, the seed box 51 is manually moved to overcome the elastic force of the volute spring 52 and rotate. At this time, the seeds stored in the cavity on the left side of the top of the seed box 51 will fall into the holes of the filter plate 53. Then, the button 57 on the lower seed plate 56 is pressed to make the lower seed plate 56 slide at the bottom of the filter plate 53, so that the holes of the lower seed plate 56 are aligned with the holes on the surface of the filter plate 53, and the seeds fall from the holes of the lower seed plate 56 into the planting grooves on the surface of the cultivation plate 14. After sowing, the seed box 51 is released, and it will automatically reset under the elastic restoring force of the volute spring 52, and the excess seeds will flow back to the seed storage cavity on the left side of the seed box 51 to prepare for the next sowing operation. Through such a design, accurate and convenient sowing function is achieved. When the cultivation plate 14 moves to the bottom of the soil covering component 6 as the chain 12 rotates, the soil stacking box 62 is driven by the internal electronic control unit of the electric guide rail b61 to move to the position above the corresponding cultivation plate 14. At this time, after the induction switch 64 senses that the position of the cultivation plate 14 is aligned with the discharge port 63, the discharge door of the discharge port 63 will be opened, and the nutrient soil in the soil stacking box 62 will be poured into the cultivation plate 14 through the discharge port 63. After the soil filling is completed, the soil stacking box 62 continues to move, driving the W-shaped scraper 65 to move synchronously. The W-shaped scraper 65 will scrape the nutrient soil that falls on the surface of the cultivation plate 14 flat to make the soil evenly distributed, and at the same time push the excess nutrient soil to the inside of the soil covering collection box 2 on the left, which is convenient for the staff to centrally handle. In addition, the staff can also pour the nutrient soil accumulated in the soil covering collection box 2 from the top of the soil stacking box 62 to replenish the nutrient soil inside the soil stacking box 62 to continue the soil covering operation.

[0030] Next, water is stored in the water tank 8. When it is necessary to irrigate the vegetables cultivated in the cultivation plate 14, the water pump 9 is started. The water pump 9 pumps the water in the water tank 8 and sprays it through the drip irrigation head 10 to realize drip irrigation of the vegetables.
